MANICURING DEVICE Original Filed Nov. 6, 1929 IZTLTEW H1255 HEaZ-ZagherPatented June 27, 1933 UNITED STATES PATENT OFFICE MILES I-I. GALLAGHER,OF CHICAGO, ILLINOIS MANICURING DEVICE Application filed. November 6,1929,=Seria1 No. 405,222. Renewed August 25, 1932.

My invention relatesin general to manicuring devices, and the object ofthe invention, briefly stated, is the production of an improved deviceof this character which is .5. rapid in operation, safe to use, andinexpensive to manufacture.

The construction of the device and its advantages will be pointed outhereinafter with reference to the accompanying drawing, in 1 which Fig.1- is a side view of the device assembled on an ordinary dentists handpiece or drill chuck; I

Fig. 2 is an end view of the same;

Fig. 3 is a bottom View of the device, detached from the hand piece;while Fig. 1 is a perspective view illustrating how the device is used.

Referring to the drawing, the reference character 2 indicates a guard ofthe form shown, made preferably of sheet metal and nickel plated orotherwise made proof against rust, as are the other parts of the de-vvice. The guard 2 is attached to a rod 3 of heavy wire which has anumber of laterally extending coils 4, which slip tightly over the handpiece 6, thereby supporting the guard in position.

The reference character 5 indicates a shaft or mandrel similar to thoseused by dentists for driving grinding tools. It extends through anopening in the guard 2. Inside the guard, the buffer wheel 7 and thesteel grinding disc 8 are secured to the mandrel in a manner similar tothe way in which dentists grinding tools are secured, being clampedbetween the cone shaped end 9 of the mandrel and the head of screw 10.The

screw 10 engages a threaded hole in the end 7 seen in 2. ably made withdifferent curvations to adapt the device for use on both large and smallfinger nails. spaced farther from the center than the other so as to.utilize a different portion of .the grinding surface of the disc 8. Thereference character 13 indicates a projec'tion at the end of the guard,which may be formed by an upsetting operation.- This projection issuitable foruse as a means of pressing back the cuticle. V The operationof the device will, no doubt, be sufliciently apparent from What hasbeen said, but may be briefly explained nevertheless. The operator willhold the device in one hand by means of the hand piece and will grasponefinger of the customer in the other hand. The Imotor may then bestarted by means of the usual foot pedal, thus rotating the buffer wheeland grinding disc. The device is then brought into position against theend of'the finger, the fingernail projecting These openings are prefer-One opening is also preferably through one of the openings 11 or 12 incontact withthe grinding disc 8, as shown clearly in Fig. 4. Then bysuitable manipulation of the devicethe finger nail is rapidly shaped upas desired. After a nail has been trimmed in the proper manner it may befinished by polishing with the buffer.

It will be seen that I have produced a highly efficient manicuringdevice, which has numerous advantages. The abrasive surface of the disc8 outs very fast, and thus a finger nail may be trimmed very much morerapidly than in the case when the ordinary file is used. At the sametime the rapidly rotating disc, which might be more or less dangerousotherwise, is rendered entirely safe by the guard in which it issubstantially It will be observed also that the enclosed. combination ofthe grinding'or cutting ele ment with the bufiing'or polishing elementmakes a very' eflicient device, combining in one too]. all the principalfunctions which a device of this character is required to perform. Fromthe mechanical standpoint'also the combination is very effective. Thebuffer wheel, being qu te substantial, serves as a support for therather flexible grlnding dlsc and renders it possible. to use the latteras pointed out, while the 'disc' does duty as a washer under the head ofscrew 10 for securing the buffer wheel to the mandrel, thus imaking fora maximum simplicity.

It will be understood that although. I have shown my improvedm'anicuring device in the form of an attachment for use in connecable toprovide a simpler form of hand piece to which the guard may bepermanently attached. with the mandrel more or less permanentlyconnected with the flexible shaft. This eliminates-the expensive drillchuck which in fact is unnecessary when the device is used solely formanicuring purposes.

Having described my invention, what I consider to be new and desire tohave proin the appended claims I What is claimed is: V I

1. A manicuring device comprising a hand piece, a buffer wheel and agrinding disc rotated by the shaft terminating in said handy-piece, saidbuffer wheel servingias a support toprevent lateral bending of saiddisc, and a guard substantially enclosing said wheel anddiscbut havingopenings through which the same may be appliedto a finger nail. v

I 2. In a manicuring device, a dischaving a grinding surface on one sidethereof, a guard tected by Letters Patent will be pointed out Isubstantially enclosing the disc andhaving an opening through which afinger nailmay be brought in contact with said disc, and means forcontinuously rotating said disc comprising a shaft extending outsidesaid guard.

3. In a manicuring device, a rotatable shaft, a bufier wheel secured tosaid shaft, a grinding, disc secured to said shaftagainst said wheel,and a guard enclosing said wheel and disc, there being an opening insaidguard to exposethe vbuiiing'surface of said wheel and a second openingto expose the grinding surface of said disc.

4. In a manicuring device, a compound grinding-and buffing-wheel havinga grinding surface on one side and a buffing surface around theperiphery,together witha guard havingan opening through which a fingernail may be trimmed bythe grindingsurface and another opening throughwhich a trimmed nail may be polished by the buffing surface.

5. In a manicuring device, a hand piece, a rotatable shaft projectingfrom said hand piece, an abrasive wheel secured to the end piece, a discsecured to the end of said shaft,

said disc having abrasive material forming a flat cutting surface on theside thereof remote from said hand piece, a housing substantiallyenclosing said disc, supporting means connecting said housing with saidhand piece, and an opening in the end of said housing through which afinger nail may be brought intoworking engagement with said cuttingsurface. V

In witness whereof, I hereunto subscribe my name this 4th day ofNovember, A. D.
